Standard Reduction Potential

Postby Nancy Le - 1F » Tue Feb 20, 2018 11:33 pm

In exercise 14.25, do the standard reduction potentials follow a periodic trend?

I was also confused by this question, I looked at Appendix 2B to try to see if there was a trend in the reduction potentials from more positive to more negative, but for part A, the Zn and Cr seemed not to follow that pattern, unless I am reading the table incorrectly?

Yes, the book states: "...the most negative-the most strongly reducing-are usually found toward the left of the periodic table, and the most positive-the most oxidizing-are found toward the upper right." Look at pg. 580 if you need further clarification.

I saw that too, and that's the answer I had originally put but I was confused because the answer from the solutions manual did not seem to follow that upper left/upper right trend. I tried doing it the method the solutions manual gave but the Cr and Zn didn't follow that rule either.
